If the direction of the torsion is changed, the movable equipment ll, l2swivels in the corresponding direction which causes the electric motorto turn the untwisting device I, in the reversed direction.

It is to be understood that without departing from the bounds of thepresent invention, other modifications and improvements in detail may befound, in the same way as the use of equivalent means may be considered.

I claim:

1. In apparatus for untwisting textile fabrics from rope form into theopen condition, a rotatable member in which the fabric rope is charged,means for rotating the same, an opening device, means for passing thefabric rope to said opening device, control means in contact with thefabric rope before it reaches such opening device, which control meansare movable by the condition and in the direction of twist of the saidfabric rope, and contact means for the regulation of movement of therotatable member which contact means are operated by the movement of thecontrol means.

2. Apparatus as claimed in claim 1, the control means in contact withthe fabric rope being grids between which the said rope passes, suchgrids being oscillatable together around the fabric rope by the twistcontained in the same, and being connected with the contact means forthe regulation of movement of the rotatable member to in accordance withthe degree and direction of twist of the rope passing between suchgrids.

3. Apparatus as claimed in claim 1, the control means in contact withthe fabric rope being grids between which the said rope passes, suchgrids being oscillatable together around the fabric rope by the twistcontained in the same, and being connected with the contact means forthe regulation of movement of the rotatable member to operate on theiroscillation such contact means in accordance with the degree anddirection of twist of the rope passing between such grids, the gridsbeing connected together and one of them being mounted upon an axiswhich is parallel to the path of the fabric rope, the other grid beingspring-controlled.

4. Apparatus as claimed in claim 1, the control means in contact withthe fabric rope being grids between which the said rope passes, suchgrids being oscillatable together around the fabri'c rope by the twistcontained in the same, and being connected with the contact means forthe regulation of movement of the rotatable member to operate on theiroscillation such contact means in accordance with the degree anddirection of twist of the rope passing between such grids, therespective grids having bars.

5. Apparatus for restoring rope fabrics to their open condition, saidapparatus comprising controlling members adapted to make contact withthe moving fabric rope and movable by and in accordance with thedirection of any twist therein, means for rotating the fabric rope tocontrol the direction of rotation of the latter for taking out thetwist, and connecting means between the first-mentioned means and thecontrolling members.
